First, the truly uncommon: Lucy Li, a 10-year-old from Redwood Shores, became the youngest player ever to advance to the USGA Women’s Amateur. Li shot 5-over-par 75 in sectional qualifying at Sequoyah Country Club in Oakland.

Li will be 10 years, 10 months and 4 days old on Aug. 5, the first day of this year’s Women’s Amateur (in Charleston, S.C.). That eclipses the record previously held by Latanna Stone, who was 10 years, 11 months and 2 days old on the first day of last year’s tournament.

Yes, these golfers keep getting younger and younger.

Li is enjoying a landmark year. In May, she became the second-youngest player in the history of the Women’s Amateur Public Links. Then, in June, she became the youngest player ever to advance to match play at that tournament.

Also on Thursday, Bryson DeChambeau of Clovis — only a few weeks removed from his runner-up finish in the California State Amateur — won the 110th Trans-Mississippi Championship at Meadow Club in Fairfax.

DeChambeau, a Modesto native, shot a final-round 69 to finish at 14-under-par. That was good enough for a five-stroke victory over Jeremy Sanders of Chatsworth and Austin Cook of Jonesboro, Ark.

Max Homa, the Cal alum and NCAA individual champion, tied for fourth at 8-under, as did USF’s Cory McElyea (who earlier beat DeChambeau to win the State Amateur).

One of Homa’s teammates this past season at Cal, Brandon Hagy, tied for eighth at 6-under.
